Get notes from the ideas or learning section
AI agents call getNotes to retrieve information from Knowledge MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing notes from designated sections of the knowledge base. It performs a query operation with no side effects, no code execution, no data modification, and no irreversible actions. The blast radius of misuse is minimal—an agent could only access information already stored in the repository.
